一是随出随施不久存。即从沼气池里取出来,直接挑到田里或土里,如果忙不过来,也只能在池外堆一两天,时间久了,速效氮会挥发掉。实验表明,沼气渣肥在露天堆放晒干,全氮损失65%左右,氨态氮损失87%。二是宜作基肥要深施。施于水田,最好是耖田时施用,使泥、肥结合,每亩施用量2000公斤左右;施于旱土,最好集中施用,如穴施、沟施,然后覆盖一层100毫米左右厚的土,以 First, follow suit soon to save. That is, taken out of the digester, directly to the fields or soil, if you are too busy, but only one or two days outside the pool, a long time, available nitrogen will evaporate. Experiments show that biogas residue fertilizer is stored in the open air and sun dried, total nitrogen loss of about 65%, ammonia nitrogen loss of 87%. The second is suitable for basal to be applied. Applied to the paddy fields, it is best to apply when the field, the mud, fertilizer, application rate of about 2000 kilograms per acre; applied to dry land, the best centralized application, such as the application of facilities, ditch, and then covered with a layer of about 100 mm Thick soil, with
